5 Oct 1993 | Subject: | cond-mat | Abstract: | We calculate the persistent current of 1D rings of spinless fermions with short-range interactions on a lattice with up to 20 sites, and in the presence of disorder, for various band fillings. We find that {it both} disorder and interactions always decrease the persistent current by localizing the electrons. Away from half-filling, the interaction has a much stronger influence in the presence of disorder than in the pure case. | Source: | arXiv, cond-mat/9310007 | Services: | Forum | Review | PDF | Favorites |
